Discussion | The habit, leaf shape, and drier habitats distinguish Hypericum lloydii from H. galioides. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Hypericum buckleyi is found throughout the southern Appalachian Mountains. The decumbent habit and persistent sepals and stamens distinguish Hypericum buckleyi from its nearest relative, H. prolificum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
